1, brand selection. Brand is everything. Choosing a brand with potential for maintaining and increasing value determines 90% of the value of this watch, but the brand appeal is not high price, but professionalism.

2. Choose materials. Whether the watch is preserved or not has a great relationship with the metal used besides the technology and brand. It is also important to know the various materials of the metal. Generally speaking, the movement of a watch is mostly made of brass, and there are four kinds of cases: gold, rose gold, platinum and platinum. Platinum is the best in price and preservation, followed by gold, rose gold and finally platinum.

3. Selection process. For a good watch, rare materials and craftsmanship can also increase the value of the watch, but besides the quality of the gem itself, craftsmanship is more important. Jewelry watches set with opal, jade, coral and diamonds, or enamel-coated dials.

4. choose exercise. The so-called watchmaking process and technology focuses on the movement. In the choice of movement, the simplest difference is that mechanical watches are absolutely superior to quartz watches. Quartz watch movement comes from IC circuit and is eliminated with the passage of time. As long as the mechanical watch is properly maintained, it will not be a problem for a hundred years. The most valuable thing about a mechanical watch is that it can display various complicated functions such as calendar, week, month, time telling, etc. through a small movement, and it also shows the unique exquisite craftsmanship of each watch factory.

5. Related restrictions. Rare things are precious. Limited edition watches have increased their collection value because of their unique and rare characteristics, and their unique numbers have greatly increased the chances of appreciation. From the brand, to the function, material, limited or not, these determine the value of a watch.
